My flight lands in Guangzhou at 4:55pm. Which port is nearest for the Pearl River cruise by taxi?

There are 3 wharfs: Tianzi Wharf, Xidi Wharf, and Dashatou Wharf. No matter which one you choose, the taxi ride from the airport should cost CNY110 - 120 and you will arrive at the wharf in 1h or so. The cruise generally lasts for 70min. After that, you can also take a taxi back to the airport. It should be easy to find a cab around the wharf. The taxi fare should be the same.
